How about a Fluke 5450A Resistance Standard. I have one and fully satisfied regaring precision, drift and tempco. Covers all your values. One is actually offered for $600 or offer with calibration, means less than $60 per value.

Partridge" <[email protected]> An: "'Discussion of precise voltage measurement'" <[email protected]> Betreff: [volt-nuts] Precision resistors Looking for a set of precision resistors for calibration purposes. I need the following values to calibrate the ohms ranges on my meters: 100 1k 2k 10k 20k 100k 200k 1M 2M 10M 20M The crucial factor isn't that they be *exactly* the values above, so I don't necessarily need 0.001% parts. Low TCR is important, and I will need to know that actual values to 10ppm or better. I'm looking for suggestions on the best choice of parts and pricing? I believe the Vishay HZ series may fit the bill for the lower values but they may be rather expensive.
